If your cowling is hazy/oxidation....

If your boat cowling has oxidation(dull finish), you can bring the shine back with some elbow grease. Mine was dull to the max. I used 3m Perfect Rubbing Compound, 3m polish and finished it off with Mothers Gold Carnauba wax. You will need a high speed buffer/sander with a compound foam pad and a polish foam pad. The end result....
